GAS-PRESSURE REGULATOR.

, Specification of Letters Patent.

Patented Mar. 28, 1916.

Application filed September l, 1915. Serial No. 48,526.

To all whom it may concern:

Be it known that I, BERNHARDT a resident of California, in the county of 'Moniteau and State of Missouri, have invented certain new and useful Improve,

ments in Gas-Pressure Regulators, of which the following is a specification.

My invention relates to means for automatically controlling the supply of gas in the degree of use, and the main object thereof is to provide such means which are an improvement over devices of thig class now known to me both structurally and in use.

It has been my experience that regulating devices of this class through which chlorin gas was passed were soon rendered useless for the reason that the chlorin gas mixed with the water in, the device to form an acid which is destructive of metals, the only liquid not so affected being sulfuric acid which is itself equally destructive of metals.

It was, therefore, to overcome the faults of the old types that my invention was conceived, as well as to provide such devices which possessed advantages not possessed by the old types, as will be hereinafter clearly set forth.

My invention is fully described in the following specification, of which the accompanying drawing forms a part, said drawing being a longitudinal, vertical, section through a gas pressure regulator constructed in accordance with my invention.

In the drawing I have shown a main tank 1 having two compartments 2 and 3 formed by a, partition 4, the latter compartment being closed at its top by means of an integral top plate 5 provided with an opening 6 closed by a removable stopper 7 provided with an air vent 8. all of these parts being made of acid resisting material, glass being one now in mind, and I also provide a drain valve 9 also formed of such material.

Detachably secured at the top of the compartment 2 is a cover 10 into which is threaded a plug 11 in direct connection with a pipe 12 leading from the tank containing the gas under pressure, not shown. and having a flared passage 13 which serves as at seat for a needle valve 14 carried'by a lever 15 pivotally carried'by a hanger 16 secured to the under side of the plate or cover 10,

and said cover is also provided with an out M. GAT- 'rnnarnm, a citizen of the United States, and

let pipe 17 controlled by a valve 18 which lea dsto the point of use ofthe gas.

The lever 15 is provided with an adjustable weight 19 at its outer end and with a dependent rod 20 which is secured to a hot-- 'low float 21 formed of acid resisting material such as glass, but the cover 10 and connected parts other than the said float may be formed of a suitable metal, copper being the one contemplated, but I do" not confine myself thereto.

The tank 1 is partially filled with liquid which may be water or may be an acid such as sulfuric which is not affected by the chlorin gas, this liquid being introduced into the tank through the opening 6 and the height or rather depth thereof'being controlled by the valve 9 so as to insure a desired relationship between the needle valve 14 and its seat. r

The gas enters through the plug 11 an 7 passes to the pipe 17 and thence to the point of use and, if the pressure of the gas should be too great, the liquid 22 in the compartment 2 is forced into the compartment 3- beneath the partition 1 to lower'the surface of the liquid in said first named compartment,athis permitting the float to descend and correspondingly moving the needle valve toward its seat to close ofl the gas supply accordingly, and, when the pressure is reduced below normal, the float rises to its limit and opens the needle valve.

In order to adjust the relationship between the valve 14 and its seat I may, as stated, add or remove liquid to or from the tank, or 1 may adjust the weight 19 toward or from the fulcrum of the lever 15, the

former being the logical method inasmuch as it avoids the necessity for removing the cover 10.

When access is desired to the parts for any reason the cover 10 may be removed and all the parts removed therewith as a unit, and it will thus be seen that no damage can result to the operator in such removal from the acid or acidulated water,

and it is not necessary to remove the liquid from the tank. 1

The material of which the tank and float are formed is thus of great importance,'and I reserve the right to use any suitable material therefor, and to make such changes in the structure as fairly come within the scope of the following claim.

lever in pivotal connection a cover for-said compartment, a hanger from -,S21ld cover supporting sald lever,

a Weight adjustablemn said lever, 2 and a floati'of acid 15 resistingimaterial connected with said lever, v excess pressure of gas forcing the liquid from the ,float compartment to .the other compartment to permit said ffioat to descend torclose said valve accordingly.
